I have latitude and longitude coordinates of stations, when I run Geolayout nodes disappear. I have read in this forum gephi has problems with longitutes near 0 and all of my nodes are near 0 (-0.1.....).
What could I do?
I attach the file
Please help!
Many thanks

As "rlike", I am having problems with importing the geographic coordinates of my network. I followed all the steps described here, but still could not organize my graph following the coordinates of my nodes. When I use "GeoAtlas" algorithm, nothing happens. I've tried three ways:
1) Like in (https://forum.gephi.org/viewtopic.php?t=1811)
- I imported my data in the format "cvs." Including two columns of coordinates, "longitude" and "latitude";
- I tried to use the "Date Lab/More Actions" and click in "Set Standard Column" and assign each column as X and Y coordinates;
- but without success with GeoAtlas.
2) Acknowledging that in the database "airlines.sample" (available here in Gephi page) the two coordinate columns were designated as "double", I tried to use the "Date Lab / More Actions" tool and "Recast Column "to change my column type. I changed the type "String" to "Double". This step resulted in two new columns, "Latitude Double" and "Longitude Double".
- I tried to use these two columns in GeoAltlas, but again without success.
3) Finally, I tried to assign these two new columns, "Latitude Doble " and "Longitude Doble", the status of standar column by "Date Lab / More Actions" click "Set Standard Column" option.
- Again it still fails.
I think I must be missing some detail because, despite trying many options, the use of Geo Atlas algorithm does not follow me any graph organized by the coordinates of the nodes.

And a WHAT'S WRONG WITH MY DATA???! question. I have the following: a date, city name, and locations indicated via longitude and latitude in degrees, with the coordinates doubled upon import of an excel sheet I saved as a csv file. With all of this in place, nodes appear, sometimes. But not at all in a visually coherent way, in accordance with the coordinates I entered. And then, when I fiddle, nothing appears at all.
Very, very simply. I want to put nodes, without edges, on a map (I've seen there's a plugin for that) in accordance with the coordinates I've already gathered. (I dreamed of time lapsing them, but that dream has been dashed by my total incompetence here.) What simple steps do I take do make that happen-- correctly?
A general comment (administrators!!): reading this forum, it looks like "newbies" have at least set foot in computer science departments and the like a few times. I have been studying literature and art all my life. I'm pre-newbie. From the level of knowing NOTHING in this arena, it is quite difficult to conceptually access Gephi via the tutorial and this forum... Maybe a Gephi for (total!) Dummies could be a good thing?!

After that, you still need to work in a spreadsheet to add these two new columns (lat and long) next to the column with the city name: with Excel or OpenCalc you have straightforward ways to do that quickly.
Ideally, this service could be integrated in a Gephiplugin, and that would not be hard to do: select a column with the adress / geographical location and two colums (lat and long) would be automatically created with the correct coordinates. But that needs a bit of time to create, and everybody is already stretched I suppose!
Best,
Clement

My question is about the GeoLayout long/lat coordinates. As of write now, I have a csv file of names, dates, cities, and associations (i.e., other people with whom each name is associated in some way). What I am looking to do is to map the relationships between this individuals for my dissertation on medieval North Africa.
While I can certainly manually change all of the city names to their specific coordinates, I am wondering if there is a way to have the program do that automatically. There are probably only 25 different locations but something like 2000 nodes. Is there a way for me to automatically have, for example, "Tunis" read and plotted on the graph as its coordinates without manually going through and adding the coordinates in a column for each node.
If this is a newbie problem (and I hope it is!), my apologies for my newness. I'm brand new to network theory and extra brand new to Gephi.

Is there a way to apply any of the ForceAtlas layout features and blend it to the GeoLayout code? and last information, I know nothing about code
Thanks

I am having trouble getting Gephi to recognize latitude and longitude when I import this data from a CSV file.
I have the latitude and longitude in columns, but when I run GeoLayout Gephi does not recognize these columns as containing latitude and longitude information. I tried adding extra columns (to make "double") in the CSV file, but this file will not load without an error of "repeating column names"...
I tried to do a round trip of the airlines sample file from Gelphi -> CSV -> import back into Gephi and the same thing is true.
What magic do I need in the CSV file?
thanks

For example, you point to Wikipedia for information on the projections for Transverse Mercator projections but that page seems to me to describe different ways of doing that projection depending on how you centre your map etc. I've even tried talking to a geographer about creating a map that would work but they say they need more information on how you do your projections to create a proper background map.
This has kind of been driving me crazy, I've tried lining up multiple maps/sociograms and can't seem to get one the lines up properly.

great plug-in! thanks so far!
My problem is the "scale" setting. I don't get it...
I have a set of nodes and everything is fine...now I wanna export it and underlay it with a map of munich.
The problem is, that I don't now which scale my map has to be. The usual scaling 1:m doesn't work because GeoLayout is referencing the scale setting to earth radius. Sorry I'm no geographer, hopefully you did get my problem.
thanks in advance!

Any chance there's a way to get this layout to work continuously such as in the same way that Force Atlas and others do?
We could add this indeed. It could be an option.Statistics:Posted by mbastian — 28 Jan 2012 19:34
